Abstract

In a device and a method for controlling an oiled air compressor (1), which is included in a compressed-air system (2) for a motor vehicle and which is driven by the engine (3) of the motor vehicle and supplies compressed air to at least one consumer (12) in the compressed-air system (2), provision is made of, on the one hand, a control unit (14) for controlling the function of the air compressor (1) by activating the air compressor at a lower predetermined pressure level (P1) for charging the compressed-air system and deactivating the same at a higher predetermined pressure level (P2) for relieving the air compressor, and, on the other, a drainage unit (17), which in connection with the activation of the air compressor (1) drains pollutants, which have accumulated in the air compressor during the deactivation, before the air compressor is allowed to start charging the compressed-air system (2).
